'4 Claims.

This invention relates to window constructions, and has for its object a sash which may be opened and closed or raised and lowered, and has easily-accessible and operable means selfcontained therewith for adjusting the sash to the variations in the widths of the'window openings or window frames of a vehicle body and to misalinements of the posts out of the vertical at e the sides of the window openings or between the window openings, so that standard sashes may be adjusted to window openings and adjustments readily made when installed for thevariations in width and for misalinements, in order that the sash may raise and lower easily under all conditions and at the same time be anti-rattling and weather tight. I i

The window openings of vehicle bodies as buses, railway cars, and the like, although intended to be uniform, vary in width, and also the posts at the sides of the window openings or between the window openings inclineout of the vertical. In some instances, these openings are somewhat key-stone in shape, and in other instances, somewhat rhomboid shape. In others, variations or combinations of these shapes. With both perfectly rectangular window openings and the irregular openings, widthwise adjustments are necessary. I

The sash equipment is furnishedby the supplier to the car builder and must be adaptable to the variations and misalinements of the window openings, in order that the sashes will'raise and lower easily and uniformly under all conditions at the same time be weather tight and also be cushioned against the weavings of the car body.

The general object of the invention is a sash structure that will conform to all these condition s. I

The inventionconsists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corr'esp'ondingparts in. all the views. i v

Figure 1 is a fragmentary elevation of a windown structure embodying this invention.

Figure 2 is a sectional view on line 2-2, Figure 1.

Figures 3 and 4 are enlarged sectional views on lines 33 and 44, Figure 2.

' Figure 5 is a sectional View onllne 55, Figure3.

Figure 6 is a view similar to Figure 3 of a slightly modified form of the invention.

I designates the car body formed with window openings confined by the inner and outer sheetings 2, 3 of the car body, and sill 4, the vertical portions of the sheeting along the sides of the window opening having inwardly extending flanges 5 constituting what are usually called posts, these posts also including additional sheeting 6 on the inner side of the car body.

In the window structure here shown, a lower stationary sash l and an upper slidable sash 8 are shown, the upper sash 8, closing down on the top rail 9 of the lower sash, this top rail serving as a sill for the upper sash. The upper sash slides upwardly from closed position.

The invention comprises means self-contained with the slidable sash and coacting with the sash guides for adjusting the sash to variations in the widthwise spacing of the guides and to misalinements of the guides and to take up or absorb weaving of the superstructure of the car or bus body without straining the sash frame. More specifically, the invention comprises a sash having its stiles slidable in the window opening and slidably interfitting with guide members mounted in the window opening or the window frame, one of, the slidably engaging parts being formed with a channel and-the other with a tongue or rib extending into the channel, and elements, as shoes, carried by the sash or the stiles thereof and coacting with the guide members at spaced apart points, these shoes or elements being adjustable independently of each other to cause the sash to coact with the guide members uniformly throughout the movement of the sash irrespective of misalinements in the window openings and the guides and variations in the width of the openings. It further includes adjusting means carried by the stiles and operable also with a channel l3 located in the plane of the sash, and also with portions, as M, ofiset from the plane of the sash for coacting with the guide member on the post 5.

In the embodiment of my invention shown in Figures 1 to 5, the guide members are shown as ribs l5 which extend into channels [6 formed in the offset portions M, each channel it being provided with a liner 16 of non-metallic flexible cushioning material, U-shaped in general form in cross section.

The means for adjusting the sash for variations in width and for misalinements of the guide members or ribs l5 comprises elements coacting with the edge of each rib l5 and means for adjusting the elements in a direction edgewise of the sash, this consisting of individual parts spaced along the stile of the sash and carried by the offset portion I l and operable from the inner edge of said portion 14 in a direction edgewise of the sash.

In the illustrated embodiment of my invention, the elements coacting with the guide rib l5 are blocks or shoes I? preferably of a non-metallic material and located in openings IS in the bottom of the U-shaped liner 56 and the adjusting members consist of screws IS threading through the inner edge of the offset portion M in a di rection edge wise of the sash or through the bottom of the channel it. The screws preferably thrust through springs 2G against the blocks or shoes ill. The heads of the screws are exposed on the inner edge of the portion Hi of the stile of the sash.

'In the illustrated embodiment of the invention, an additional strip M is secured to the bottom of the offset portion E4 of the stile, as by screws 22. The adjusting screws l9 thread through the strips. The outer ends or heads of screws iii are suitably formed to receive a tool, they being here shown as formed with a socket 23 for receiving a wrench. The upper and lower ends of the channel 56 are closed by cover strips lii which hold the liner from endwise displacement.

Each rib l5 projects from a suitable base plate 24 which is secured to the post structure by interlocking one edge or lip at 21 under an overhanging flange 23 on a strip 29 secured to the post structure, as by screws 36, and by screws 3i extending through the base plate and into the post structure after the edge or lip 27 has been interlocked under the flange 28. A rack 32 is secured to the base plate and extends into the channel 53 of the sash, this rack coacting with the bolt 33 of a sash holder located within the bottom rail of the sash 8 and operable by a lever 34' on the outside of the rail.

The lower stationary sash l is similar in construction to the upper sash 8 with the exception that it being stationary, no provision is made for raising and lowering it or for misalinements and widthwise adjustment. The sash 8 is provided with a suitable weather stripping 35 along its top rail for rendering it weather tight when the sash is closed.

In Figure 6, the guide 16 is shown as, channelshaped for receiving the stile ll of the sash, as the cushioning strip t2 embraces the stile 4| and is carried thereby. The shoes 43 are located in openings M in the bottom of the U formation of the cushioning strips G2. The shoes t3 are individually adjustable by screws 45 threadinginto the offset portion 46 of the sash or stile, in a direction edgewise of the sash. They thrust against th furnished by the manufacturer, to the car builder and the sash is accurately rectangular. The guide equipment is also furnished by the sash manufacturer. The car builder first secures the strip 29 to the post structure and then applies the sash guide with a sash therein by inserting the base flange of the sash guide under the flange 28 of strip 29, and then applies the screws 3 I. He then manipulates 'theadjusting screws 23 for the widthwise adjustment and for adjustment as to misali'nements, so that although a window opening may be a trifle key-stone or rhomboid shape, or variations of these shapes, the adjustment may be made by, means of screws I9, so that the sash slides vertically under all conditions and with uniform pressure and without looseness.

Owing to this adjustment and to the springs ii), the sash adapts itself to misalinements and raises andlowers or operates easily under all conditions and also the sash is protected by the spring arrangement against undue strains, due to weaving of the car body and also the resilient liner protects the sash againsttransverse strains clue to weaving.
